Description
| Product Name: | Human IFN a 2b Recombinant Protein |
| Product Code: | RPPB0385 |
| Size: | 50µg |
| Species: | Human |
| Target: | IFN a 2b |
| Synonyms: | Interferon alpha 2b, IFNA, INFA2, IFN-? 2b, MGC125764, MGC125765. |
| Source: | Saccharomyces cerevisiae |
| Physical Appearance: | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation: | Lyophilized from a 0.2?m filtered concentrated (1mg/ml) solution in PBS, pH-7.4. |
| Solubility: | It is recommended to reconstitute the lyophilized glycosilated IFN alpha 2b in sterile 18M?-cm H2O not less than 100�g/ml, which can then be further diluted to other aqueous solutions. |
| Stability: | Lyophilized glycosilated IFN-a 2b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN-alpha 2b should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
| Purity: | Greater than 98.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
| Amino Acid Sequence: | The sequence of the first five N-terminal amino acids was determined and was found to be Cys-Asp-Leu-Pro-Gln |
| Biological Activity: | The specific activity as determined in a viral resistance assay was found to be no less than 300,000,000IU/mg. |
| UniProt Code: | Q86UP4 |
IFN-alpha is produced by macrophages and has antiviral activities. Interferon stimulates the production of two enzymes: protein kinase and an oligoadenylate synthetase.
Interferon-alpha 2b Human Recombinant produced in yeast is a single, glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of approximately 19 kDa.The Interferon-alpha 2b gene was obtained from human leukocytes.The IFN-a 2b is purified by proprietary chromatographic techniques.
